Abstract

The temperature response of hydrogels made from hydrophobically modified water soluble polymers is complicated by the fact that while the hydrophobilic backbone becomes dehydrated and thus less compatible with aqueous solvents as the temperature is increased, the hydrophobic side chains become more compatible. These opposing effects taken together will govern gel properties such as volume, storage modulus, etc. We will discuss the effects of temperature on the composition, volume and reheological properties of hydrogels made from hydrophobically modified hydroxyethyl cellulose (HMHEC) in aqueous solutions containing the surfactant sodium dodecyl sulfate (SDS).
